Riser fluid handling system

摘要

A fluid handling system comprising an annular sealing device and a flow control system to divert fluid flow from an annulus of a riser package to a control system located on a rig. A method of installing a fluid handling system on a riser package from a rig comprises connecting the fluid handling system to an upper end of a riser string, supporting the fluid handling system and the riser string using a first tubular handling device, and lowering the fluid handling system and the riser string to an operating position.

主权项

1. A riser package for use on a rig, comprising:
a rotating control device coupled below a telescopic joint and having a rotating seal operable to sealingly engage a tubular string disposed through the riser package; an annular sealing device coupled below the rotating control device, wherein the annular sealing device is operable to close off the entire flow bore of the annular sealing device to prevent fluid from flowing up through a flow bore of the riser package past the annular sealing device; a flow control device coupled below the annular sealing device and having one or more first control lines that provide fluid communication between the flow control device and a control system located on the rig, wherein the flow control device is operable to divert fluid flowing up through the flow bore of the riser package to the control system located on the rig via the first control lines; a riser string coupled below the flow control device; and a blow out preventer coupled below the riser string and having one or more second control lines that provide fluid communication between the blow out preventer and equipment located on the rig.
